I am looking to purchase a total of 200 ECG machines to meet our current demand. Specifically, I need 150 units of a 3-channel model and 50 units of a 12-channel model. It's essential that these machines are reliable and come with the necessary certifications for medical use. Please provide me with your best pricing, lead times, and any available warranty information. Additionally, if you have any recommendations for related accessories or software that complement these ECG machines, please include those details as well. I look forward to your prompt response so we can move forward with this order.
